[0132] like Figure 6 As shown, as a preferred embodiment of the utility model, the motor control module includes a field effect transistor Q5, a field effect transistor Q6, a field effect transistor Q9, a resistor RS9, a resistor R65, a resistor R58, a resistor R45, a resistor 50 and a resistor 44;

[0133] The G1 interface of the field effect tube Q5 is connected to the H_DW interface of the chip U5, the S1 interface is connected to the cathode of the diode D1, the G2 interface is connected to the L_DW interface of the chip U5, S2 is connected to the second ground wire through the resistor RS9, and the D1 and D2 interfaces are connected to the W phase of the motor;

[0136] The S2 interface of the field effect transistor Q5, the S2 interface of the field effect transistor Q6, and the S2 interface of the field effect transistor Q7 are connected to the AMP0P interface of the chip U5 through the resistor R65;

[0137] One end of the resistor R58 is connected to the second ground line, and the other end is connected to the AMP0M interface of the chip U5;

[0138] One end of the resistor R45 is connected to the first AD interface of the chip U5, and the other end is connected to the second ground line through the resistor R50;

[0139] One end of the resistor R44 is connected to the cathode of the diode D1 , and the other end is connected to the second ground line through the resistor R50 .

[0140] In the embodiment of the utility model, capacitors and resistors required for forming the circuit and protecting the circuit are also included. For example, a resistor is connected in series between the G1 interface of the field effect transistor Q5 and the H_DW interface of the chip U5, and the resistor is used to limit the current of the G1 interface of the field effect transistor Q5 to protect the field effect transistor Q5. The same is true for other interfaces.

[0141] In the embodiment of the utility model, the first output voltage is conducted to the second ground line through the switch of the field effect tube Q5 or the field effect tube Q6 or the field effect tube Q9, and the resistor RS9 is set to sample the current I_shunt. Through the FOC algorithm control, the switching time of the field effect tube Q5 or the field effect tube Q6 or the field effect tube Q9 is calculated to realize the control of the motor. At the same time, the current here can be used as the current for detecting the entire current loop, providing data for the chip U5 program, thereby realizing overcurrent protection. The chip U5 integrates a high-performance operational amplifier, the AMP0P interface of the chip U5 is the same direction end of the operational amplifier, the AMP0M interface of the chip U5 is the reverse end of the operational amplifier, the sampled current I_shunt amplifies the voltage through the operational amplifier, the AMP00 interface of the chip U5 is the output end of the operational amplifier, and the chip U5 samples the voltage of the AMP00 interface to calculate the bus current value of the current motor load.

Therefore, once the voltage of AMP00 is greater than the set value, the output signal of the comparator directly cuts off the motor control signal of chip U5 to the motor control module to protect the motor control module and the motor. The first output voltage is divided by resistors R44 and R50 to reduce the voltage to a voltage that can be detected by the main control chip, realizing overvoltage and undervoltage protection, and providing signals to the FOC algorithm. It also provides stall protection and phase loss protection functions.

[0142] In the embodiment of the utility model, the field effect tube Q5 has a dual MOS tube, and the field effect tube Q6 and the field effect tube Q9 are the same as the field effect tube Q5. Through the pulse width modulation (PWM) technology, the switching time of the field effect tube Q5, the field effect tube Q6 and the field effect tube Q9 is controlled to adjust the input voltage and current of the motor. The duty cycle of the PWM signal determines the average voltage of the motor, which in turn affects the speed of the motor. Here, the PWM signal sent by the chip U5 to the field effect tube Q5, the field effect tube Q6 and the field effect tube Q9 is the motor control signal, which is a prior art and will not be described in detail here.

[0143] like Figure 7 As shown, as a preferred embodiment of the utility model, the light board control module includes a MOS tube Q7, a MOS tube Q20, a resistor RS10, a resistor RS11, a resistor R103 and a resistor R104;

[0144] The G pole of the MOS tube Q7 is connected to the second IO interface of the chip U5, the D pole is connected to the first negative pole of the light board, and the S pole is connected to the second ground line through the resistor RS10 and connected to the second AD interface of the chip U5 through the resistor R103;

[0145] The G pole of the MOS tube Q20 is connected to the third IO interface of the chip U5, the D pole is connected to the second negative pole of the light board, and the S pole is connected to the second ground line through the resistor RS11 and connected to the third AD interface of the chip U5 through the resistor R104.

[0146] In the embodiment of the utility model, the capacitors and resistors required for forming the circuit and protecting the circuit are also included. For example, a resistor is connected in series between the G pole of the MOS tube Q7 and the second IO interface of the chip U5, and the resistor is used to limit the current of the G pole of the MOS tube Q7 to protect the MOS tube Q7.

[0147] In the embodiment of the utility model, MOS tube Q7 controls the LED lamp emitting white light in the lamp board, and MOS tube Q20 controls the LED lamp emitting yellow light in the lamp board. Since the positive electrode of the lamp board is connected to the positive electrode of the output end of the second buck module, when MOS tube Q7 is turned on, it is equivalent to the first negative electrode of the lamp board being connected to the second ground wire, and the LED lamp emitting white light in the lamp board forms a loop, so the LED lamp emitting white light in the lamp board is lit, and the intensity of the lighting is determined by the on-off cycle of MOS tube Q7; when MOS tube Q20 is turned on, it is equivalent to the second negative electrode of the lamp board being connected to the second ground wire, and the LED lamp emitting yellow light in the lamp board is formed into a loop, so the LED lamp emitting yellow light in the lamp board is lit, and the intensity of the lighting is determined by the on-off cycle of MOS tube Q20. MOS tube Q7 and MOS tube Q20 can be turned on at the same time, so that the LED lamps emitting white light and yellow light in the lamp board are lit at the same time, showing different colors according to the degree of lighting.

[0148] In the embodiment of the utility model, the chip U5 outputs a PWM signal with a certain frequency and different duty cycle. The PWM signal controls the on and off of the MOS tube Q7 and the MOS tube Q20, thereby controlling the power of the light board power supply and the brightness of the different color lamp beads on the light board. Since the input voltage is the third DC voltage, and the third DC voltage is a constant voltage source, when the light board is driven, the temperature of the LED lamp on the light board will rise. If it is not restricted, the light board will reduce the luminous efficiency, produce obvious light decay, and cause damage. Resistors RS10 and RS11 are set to detect the current in the loop. Once it exceeds a certain value, the duty cycle of PWM is reduced, and the current passing through the light board is reduced, thereby reducing the heating of the light board and extending the life of the light board. Here, the PWM signal sent by the chip U5 to the MOS tube Q7 and the MOS tube Q20 is the light board control signal. The PWM signal of the MOS tube Q7 is controlled by the second IO interface of the chip U5. The PWM signal of the MOS tube Q20 is controlled by the third IO interface of the chip U5. The current detection in the loop is transmitted to the chip U5 through the second AD interface and the third AD interface of the chip U5, and the second AD interface and the third AD interface of the chip U5 also have the function of IO interface. The resistors R103 and R104 are provided to protect the chip U5.

[0152] The positive electrode of the buzzer B1 is connected to the C electrode of the transistor Q4, and the negative electrode is connected to the second ground line.

[0153] In the embodiment of the utility model, when the communication module communicates with the chip U5, for example, when receiving the communication data of the motor shifting, the fourth IO interface of the chip U5 will transmit a signal to turn off the transistor Q14, turn on the buzzer B1, and emit a prompt sound.

[0155] The fan blades are fixed to the rotating shaft of the motor to realize the blowing function of the fan lamp;

[0156] The motor is connected to the control assembly and is used to control the rotation of the fan blades to achieve the blowing function of the fan lamp;

[0157] The light board is connected to the control assembly and is used to realize the lighting function of the fan light;

[0158] The control component includes a fan lamp control circuit with stepless dimming and color adjustment as described above, which is used to control the rotation of the motor and regulate the light panel for stepless dimming and color adjustment to control the operation of the fan lamp.

[0159] In the embodiment of the utility model, the on and off of the motor and the on and off of the light board are two independent control circuits, that is, the motor and the light board can be turned on or off at the same time, or only one of them can be turned on.

[0160] The fan lamp provided by the embodiment of the utility model receives an external remote control signal through a communication module and decodes it to generate communication data, and sends the communication data to the main control module; the main control module sends a motor control signal to the motor control module according to the communication data and the first feedback data, and sends a light board control signal to the light board control module according to the communication data and the second feedback data; the motor control module controls the rotation of the motor according to the received motor control signal, and sends the first feedback data to the main control module; the light board control module performs stepless dimming and color adjustment on the light board according to the received light board control signal, and sends the second feedback data to the main control module.
